electrical arc can occur. This could cause an explosion in hazardous area installations. Be sure
that all power is removed from the switch and any other circuits. Be sure that power cannot be
accidentally turned on or verify that the area is nonhazardous before proceeding. Statement 1058

connectors.
When you are testing the switch, one power source is sufficient. If you are installing the switch and are
using a second power source, repeat this procedure for the second power connector (DC-B), which
installs just below the primary power connector (DC-A).
When you are installing the switch, secure the wires coming from the power connector so that they
cannot be disturbed by casual contact. For example, use tie wraps to secure the wires to the rack.

Applying Power to the Power Converter

Move the circuit breaker for the AC outlet or the DC control circuit to the on position.
The LED on the power converter front panel is green when the unit is operating normally. The LED is
off when the unit is not powered or is not operating normally. After the power is connected, the switch
automatically begins the power-on self- test (POST), a series of tests that verifies that the switch
functions properly.
Running Boot Fast
When the switch powers on, it automatically initiates a boot fast sequence. To test the switch, follow the
steps in these sections:

Powering On the Switch

To apply power to a switch that is directly connected to a DC power source, locate the circuit breaker on
the panel board that services the DC circuit, and switch the circuit breaker to the ON position.
